Ah yes, the taller vehicles I have come across - whether in my Rear View Mirror or coming right at me on my normal short trips out and about. How do they PASS an MOT then? They don't need one for the first 3 years so maybe why it's just coming to light. Just in case you don't know by the way - don't consider changing your "Normal" Bulbs for LED ones, even if Adapters are mentioned - you can damage your Battery and Electronics if things go wrong.
